UNITED STATES PATENT OFFICE.

ANTONE CONSTANTIN, OF NEW YORK, N. Y.

Patented Sept. 6, 1921.

To all w ham it may concern Be it known that I, ANTONE CONSTANTIN, acitizen of the United States, and a resident of the city of New York,borou h of Manhattan, county and State of New ork, have invented a newand Improved Insecticide, of which the following is a full, clear, andexact description.

This invention relates to insecticides, and has for an object theprovision of an insecticide which is highly poisonous to insects, andwhen placed in an infected region will remain in place for long periodsof time without being blown away.

My improved insecticide is especially valuable in the extermination ofbed bugs and other house pests. There are many compositions for asimilar purpose sold commercially, but most of these are in a powderedform and when sprinkled around in a room or house which is infected, thedust is carried around by the air and due to its highly poisonouscharacter, is often detrimental to the health of human beings. In myimproved insecticide, I provide a vehicle which will give the resultingcomposition a salve like character, so that when spread upon a surface,it will firmly hold the poisonous ingredients and. prevent them fromentering the air which is breathed in by the occupants of the house.

I have discovered that green paint powder and yellow paint powder bothhave very poisonous properties toward bed. bugs and other house pests.Yellow paint powder consists primariliy of chromate of lead having theformula bCrO,, and the green paint )owder is a mixture of chromate oflead,

'russian blue called ferric ferrocyanid, and having the formulaFe,(Fe(Cl\) and barytes. These are generally mixed in the followingproportions: chromate of lead,

Application filed March 26, 1920. Serial No. 369,078.

Lard 8 parts Soap 1 part Yellow paint powder 1 part Green paint powder 1part The lard and the soap act as a vehicle which gives the finalcomposition a salve like character, and also serve to attract theinsects to the composition upon which they feed. Any other suitableingredients may be used which will accomplish the same result, andfurthermore, the proportions in my composition can be variedconsiderably with more or less successful results. The ingredients aremixed thoroughly together in any order, preferably with the aid of heat.

I would state in conclusion that while the example described constitutesa. practical embodiment of my invention, I do not limit myself strictlyto the aforementioned cictails since manifestly the same can beconsiderably varied without departure from the spirit of the inventionas defined in the ap ended claim.

Iaving thus described my invention, I claim as new and desire to secureby Letters Patent:

An insecticide, wntaining lard, soap, chromate of lead, ferricfcrrocyanid, and barytes in about the proportions s ecified.
